Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The package is an observability plugin and sends replay to its local bridge, but it silently enables session recording by default and disables masking for password and other form inputs. This is undisclosed runtime telemetry with a material risk of capturing sensitive user-entered data, so it warrants a warning rather than a malicious verdict. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 92.0% - **Started:** 2026-10-29T20:58:05.671Z - **Finished:** 2026-10-29T20:59:17.288Z - **Download time:** 260 ms - **Static scan time:** 59 ms - **AI review time:** 71297 ms - **Total time:** 71617 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Undisclosed default browser session replay can collect page content and unmasked form values, including password input, and send them to the local LensMCP bridge. - **Trigger:** A Vite development server using the plugin serves its injected client; replay is enabled unless explicitly disabled or configured off. - **Impact:** Sensitive values entered into the observed application may be recorded and made available to the local LensMCP runtime without an explicit replay opt-in. - **Evidence paths:** lib/replay-setting.js, lib/plugin.js, .lpm-dependency-evidence-864755eb-8cca-4cb8-a8d0-708576fac8a7/1/npm-linux/replay-source.js - **Review source:** ai\_review - **Reviewed:** 2026-10-29T20:59:17.288Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The replay recorder captures browser session data with general input masking off and password masking explicitly disabled, then POSTs replay payloads to the bridge endpoint. - **Rationale:** The package is an observability plugin and sends replay to its local bridge, but it silently enables session recording by default and disables masking for password and other form inputs. This is undisclosed runtime telemetry with a material risk of capturing sensitive user-entered data, so it warrants a warning rather than a malicious verdict. - **Network endpoints:** ws://127.0.0.1:\, http://127.0.0.1:\ ### Review decision - **Verdict:** Suspicious - **Confidence:** 92.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Replay is enabled by default when no option or environment setting is supplied and the capture configuration is absent or unreadable., When enabled, the plugin passes replay configuration into the injected browser runtime and constructs its replay endpoint from the bridge host and port., The recorder defaults to leaving inputs unmasked and explicitly disables password masking; it sends replay data with HTTP POST., The bridge host defaults to 127.0.0.1 and the port is selected locally when unspecified. - **Evidence against:** The package describes itself as a frontend observability plugin that streams browser events to LensMCP., The plugin normally attaches to Vite's development server, and the inspected replay transport targets the local bridge; no unrelated external collector was identified. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.25.37. - Review the evidence and your use of @lensmcp/vite-plugin@1.25.37 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
